121052-02-6 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 121052-02-6 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,2,1,0,5 and 2 respectively; the second part has 2 digits, 0 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 121052-02:
(8*1)+(7*2)+(6*1)+(5*0)+(4*5)+(3*2)+(2*0)+(1*2)=56
56 % 10 = 6
So 121052-02-6 is a valid CAS Registry Number.
